This is a set of 4.0 liter aluminum V6 cylinder heads that came in off of a Ford Explorer. We blasted them clean, did a pressure test on them to make sure they weren’t cracked or leaking, and then gave them a three angle valve job on our Tobin-Arp seat-and-guide machine. We then milled their surfaces flat and square before assembling them with a set of new positive Viton valve stem seals.
